Hi everyone,
I've been working on a wad started by Eric Schrock a couple years ago to
add type information to MDB pipelines. It has blossomed into a fairly big
modification of the MDB module API, and I'd like to get some community review
before I put this back.
I took a look at some of the changes, and the arc case materials and
this looks
great. I have a question about arguments to walkers. You specifically show
using arguments with kmem related walkers. So, this will allow me to do:
> ::walk kmem -n kmem_alloc_8192
or
> ::walk kmem_alloc_8192
or
> address::walk kmem
Where address is the address of the kmem_alloc_8192 cache from
the ::kmem_cache command. I expect all 3 of the above to give
the same output. Or, is this different? Has the same thing been
done for the various zio_buf walkers (I can't find these walkers in the
source code), the ire walkers, others?
Also, in the above, I should be able to:
> walk kmem_alloc_8192 | ::print
and it will automatically know to print out a kmem_cache_t (or whatever)?
Can I do this:
::pgrep foo | ::print p_as | ::walk seg | ::print s_data
(as another example)? From my understanding of the arc materials,
I should be able to do the above, or am I missing something?
thanks,
max
